You cannot tell from TTN Console if the device received it. You only know that TTN wanted a gateway to transmit it. (Might also be another gateway if your uplink was received by multiple gateways.)
Again: your device is waiting for the downlink, but not receiving it.
Some single-channel test gateways do support downlinks, so one could say it’s the software of your gateway.
(Also, your device should not ask for a confirmation for each uplink, see Fair Use Policy explained)
